NoN-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 18, 1967',

Application filed December 3,1906. Serial No. 846,138.

' non-reillable bottles having c osing devices of the kind rovided with an internal sleeve shaped to t the neck of the bottle and adapted to engage with a shoulder or in a groove or recesses formed in the said neck, a hollow lvalve provided with a tapered lower end, and a protecting cap designed to fit into the top end of the -sleeve and formed with va hollow depending stem designed to extend down into the interior of the valve when in its normal position.

According to my invention I provide the valve withguide-ribs to guide it within the sleeve and I construct the cap, so that it can be spread or formed to engage the groove, shoulder or recesses in the bottle neck with which the sleeve engages. I also provide perforations in the iiange 'formed around the stem of the cap and a spring between the latter and the valve.

Figure l, is a sectional perspective view showing the neck portion of a bottle and my improved device for preventing the non-refilling of the same. Fig. 2, is a similar view showing the device provided with an alternative form of protecting cap. Fig. 3, is a detail of the internal sleeve adapted to fit the neck of the bottle. Fig. 4, is a detail of the valve. Fig. 5, is a detail .of the protecting cap.

In the drawings like letters of reference indicate corresponding parts in each iigure.

.A is the internal sleeve, which is adapted to iit the neck of the bottle being in the form shown or any other desired Jform. The bottom of the sleeve, however, is rovided with a tapered reduced portion A ieaving a narrow shoulder A2 surrounding the same at the top. The upper end of the sleeve iiares outwardly at As and is by any'suitable instrument pressed into the groove B formed in the bottle and necessarily under the shoulder forming the top side of the groove.

C is the valve, which is closed at the bottom and is hollow and tapered as shown and formed with guiding ribs C', which are designed to guide the valve in its longitudinal movement Within the cylindrical portion of the sleeve A.

D is the protecting cap or cover for the de-` vice, which is formed as shown in Fig. l, with an outwardly extending flange D', which is spread to iit in the groove Bin the neck of .the bottle and under the shoulder formed thereby. The protecting cap D is rovided with a perforated upwardly exten ing central portion D2 from the top of which depends the hollow stem D, which is provided with a hole D4 near or at the bottom and within the valve C.

2 is the spiral spring, which extends between the cap D, the stem D3 of which it surrounds, and the valve C as indicated. The spring 2 is designed to force the valve on its seat when the bottle is partially tipped, that is to say when it is more on its side but is not of sui'licient strength to Jforce the valve on its seat when the bottle is in the inverted position.

If the spring were not provided there might be a liability of the valve not closing when the bottle is on its side and the spring insures of thevalve closing should it be attempted to ill the bottle when it is on its side. Of course, the valve would naturally iioat up if the bottle were inverted and the spring is weak enough so that it will not support the weight of the valve when the liquid is being poured out.

In Fig. 2, I show the upper portion of the protecting cap D substantially reversely formed to that shown in Fig. 1, such protecting cap in this case being formed with the upwardly extending central portion D5 of a greater diameter than the hollow stem and perforated as shown, the horizontal portion D at the top, the depending portion D7 adapted to fit the neck of the bottle and provided with lips'D8 punched out of the flange D7 and iitting underneath the shoulder in the neck and the inwardly extending flange D9.

The obfect of both the protecting caps shown in Figs. 1 and 2 is to prevent the insertion of wires by which the free movement of the valve might possibly be prevented, and yet allow of the free escape of the liquid.

I shall now describe the utility of my device.

IOO

Should it be desired. to pour out the liquid the bottle being tilted the valve (l will pass off its seat being held in proper position in its longitudinal inoveinent'in the neck by the guides'C. The liquid will pass out around the annular space between the valve and the cylindrical portion. of the sleeve A and through the perforated iiange D2. The hole D4 in the hollow stem will permit of the air xo to pass inwardly so that the free pouring out of the liquid. is facilitated, such hole prevent ing the liquid from passing down quickly and filling the space around the stein and possibly throwmg back the valve on its seat i 5 when the liquid is being poured. out.

Should it be desired to refill the bottle the pressure of the liquid in no matter what way the bottle may loe inverted would iioat the hollow valve uickly up on its seat, the air 2o forced in by Ehe liquid being facilitated in its passage to the valve by the hole D4, so that before the liquid can reach the opening between the valve and its seat it will have,

through the medium of the air in the valve floated the valve back to its seat. Should,

however, the bottle be in a substantialljy horizontal position or a tilted. position the preponderance of the weight of the liquid.

will force the valve back quickly on to its o seat and thereby prevent the liquid frein.

passing into the bottle and this it will be understood would arise from the fact of the larger area of the valve as compared with the annular space between it and the sleeve.

The material, which I niake the device of is preferably aluminium although, of course, any other suitable material may be used.

Although I show lips D8, in Fig. 2, it will be understood that such lips may be used in.

the form shown in Fig. 1, instead of flaring 4o the top ol.' the ii'iternal sleeve.

What l claim as my invention is:

1.. .ln a noi'i-relillal'ile bottle, in combination a sleeve adapted to iit the neck `of the bottle and provided with a reduced tapered loworportion, a hollow iinperforate valve provided with a suitable bottoni and tapered lower [x'irtion, guiding ribs upon the valve and a protecting cap fitting the upper portion of the l sleeve and suitably secured in place and. provided with a depending stem eXtending into the valve and having a hole therein7 the stein of' the valve having perforations in the [lange surrounding the saine and the sleeve being adapted to engage a groove in the neck of the bottle as and for the purpose specified..

2. In a non-refillable bottle, i'n combination a sleeve adapted to fit the neckof the bottle and provided with a reduced tapered lower portion, a hollow iinperforate valve provided with a suitable bottoni and tapered lower portion, guiding ribs upon the valve and a'proteeting cap iitting the upper portion of the sleeve and suitably secured in place and provided with a depending stein extending into the valve and having a hole therein, the stein of the valve having perforations in the iiange surrounding the saine and the sleeve being adapted to 4engage a groove in the neck of the bottle, anda spiral spring extending from the cap to the bottoni of the hollow valve as and for the purpose specified.
